General Electrical Diagnostic Information

Machine electrical schematics and wire harness diagrams are necessary for troubleshooting machine
circuits. The schematics and diagrams are available in the service manual for your machine (Greensmaster®
e1021/e1026 Service Manual or Greensmaster® eFlex® 1021 Service Manual).
The Greensmaster eFlex 1021 and e1021 use a 48V battery-based electrical system. The voltage will vary,
depending on the charge level of the battery.

Ground Connection for Troubleshooting

Important:
The machine frame is not used as an electrical ground. Ground is distributed through the
machine wiring.
An easy-to-use electrical ground is the negative terminal on the battery controller.

2. Negative terminal (ground)
